Narrative
Averaged 40 cm in height and exhibits an indeterminate Type IIIa growth habit, with pod distribution throughout the plant canopy. Produces white blossoms and flowers 45 d after planting, although flowering is delayed at elevations above 2,300 masl in the sub-humid highlands. Is a mid-season cultivar, maturing 94 d after planting with a range in maturity from 90 to 99 d, depending on season and altitude. Carries the single dominant hypersensitive I gene for resistance to Bean Common Mosaic Virus but is sensitive to the necrosis inducing strains of Bean Common Mosaic Necrosis Virus, which induces the black root reaction. In Central Mexico, it has not exhibited field symptoms of anthracnose or rust in spite of the large number of physiological races detected in the region. Resistant to local isolates of halo blight, and is tolerant to local isolates of common bacterial blight, and root rots in the highlands. Produces a typical flor de mayo seed with a pink/purple marbled pattern on a cream background. Seed size is medium and averages 28.3 g/100 seed, ranging from 27.6 to 32.3 g/100 seed depending on location. The seed is similar in size, shape and color to common highland landraces in the flor de mayo class, but larger in size than Flor de Mayo Bajio. Average cooking time is slightly longer (66 min) than the time for Flor de Mayo Bajio (61 min), but is less than the time for Flor de Mayo M38 (71 min).
